AAttention deficit hyperactivity disorder (ADHD) is a common childhood illness. In some patients, this illness may persist into adulthood and an association between ADHD and Obstructive Sleep Apnea (OSA) has been found in childhood. However, it is unclear how OSA and ADHD coincide in adulthood. Therefore, to explore the relationship between OSA and adult ADHD the current investigation utilized a clinically-based cross-sectional survey. Subjects consisted of 81 treatment-naïve OSA patients and 32 controls. Measures included each patient completed a questionnaire regarding sleep, Adult ADHD scale. Clinical information, body mass index, 36-item Short Form Health Survey (SF-36), Epworth Sleepiness Scale (ESS), Hospital Anxiety and Depression Scale, and polysomnography.The subjects with Apnea-Hypopnea Index (AHI) ≥ 5 events/h were defined as patients with OSA. The control group was accepted as individuals with AHI > 0 events/h. The prevalence of adult ADHD was not different between the patients with OSA and the control group [(7.4 % (6/75) vs. 6.3 % (2/30), p = 0.8, respectively]. OSA patients with ADHD, as compared with those without, had higher anxiety scores and poorer physical component scores of quality of life and higher ESS scores. ADHD scores in patients with OSA were associated with anxiety and depression scores and SF36 physical and mental component scores in bivariate analyses. Thus, in our sample ADHD was not a frequent illness in adult patients with OSA. However, in patients with OSA and ADHD higher levels of anxiety and daytime sleepiness and poorer quality of life was found.

Present study indicated that patients with OSAS compared to snorers displayed significantly more hyopchondriasis and psychopathic deviance personality characteristics. The daytime functions in individuals with sleep-disordered breathing may be influenced by the severity of psychopathology.

Microalbuminuria may be seen in patients with OSAS, depending on the severity of disease and hypoxemia. Microalbuminuria in patients with OSAS should be examined in regular periods for risk of cardiovascular morbidity or mortality.

Objective: To investigate the relationships between metabolic syndrome (MS), other metabolic features and left ventricular mass index (LVMI) in a population of obese children and adolescents with MS. Methods: Two hundred and eight obese children and adolescents (119 females and 89 males, mean age: 11.9±2.7 years) and control subjects (24 females and 26 males, mean age: 11.4±2.9 years) were enrolled in the study. The insulin sensitivity index and LVMI were determined. The International Diabetes Federation criteria were used to diagnose MS.Results: The obese patients were divided into MS group (n=55) and non-MS (n=153) group. The values of LVMI in the MS group were significantly higher than those in the non-MS group (p=0.014). The present LVMI cut-off point of 33g/m2 for the diagnosis of MS yielded a sensitivity of 97% and a specificity of 98%. LVMI was found to be positively correlated in univariate analysis with height, weight, body mass index (BMI) SDS, fasting insulin level, homeostasis model assessment of insulin resistance (HOMA-IR) and fasting glucose to insulin ratio (FGIR) and negatively correlated with quantitative insulin sensitivity check index (QUICK-I). Conclusions: We suggest that our optimal LVMI cut-off value for identifying MS may be considered as a sensitive index in screening obese children and adolescents for pediatric MS. Assessment of LVMI in obese children and adolescents may be used as a tool in predicting the presence of MS and its associated cardiovascular risks. Conflict of interest:None declared.

BACKGROUND: Bronchiectasis may change cognitive function. The mechanism responsible for cognitive dysfunction in COPD may be neuronal damage caused by hypoxia. Cognitive function in patients with bronchiectasis is also likely to be affected by similar mechanisms. The goal of this study was to determine the frequency and determinants of low cognitive ability in subjects with stable bronchiectasis. METHODS: Thirty subjects with stable bronchiectasis and 25 healthy volunteers underwent a cognitive ability assessment using the Wechsler Adult Intelligence Scale. Bronchiectasis was diagnosed by high-resolution computed tomography of the chest. Age, body mass index, the Hospital Anxiety and Depression Scale, and pulmonary function were assessed. Perceived intensity of dyspnea after exercise (after climbing 3 flights of stairs) was estimated using a modified Borg scale. RESULTS: Mean scores on the verbal and performance tests and full-scale IQ scores were significantly lower in subjects with bronchiectasis than in healthy volunteers. Low cognitive ability in subjects with bronchiectasis was associated with higher depression scores, lower oxygen saturation, and poor lung function after adjusting for potential confounders in multivariate analysis. Borg scores after exercise in subjects with bronchiectasis and low cognitive ability were higher than those in subjects with bronchiectasis and high cognitive ability, despite similar P aO 2 and FEV 1 in both groups. CONCLUSIONS: Low cognitive ability in subjects with bronchiectasis may be associated with reduced lung function, more serious hypoxemia, and higher depressive symptoms. Subjects with bronchiectasis and low cognitive ability feel more intense dyspnea than do those with high cognitive ability.
